SSD Upgrade: Not Able to Boot from New SSD Disk
Do you encounter the problem that not able to boot from new SSD after upgrading HDD to SSD? This post will give you some suggestions when SSD won’t boot after clone.
I want to upgrade the hard disk for my Windows 10 laptop HDD to SSD, but I do not want to reinstall Windows OS and the applications. Here is the thing, I tried to clone my HDD to the new SSD. After clone, I removed the HDD and installed the SSD. However, when I started my laptop I found the SSD won’t boot after clone and I got the message as “no bootable device found”. What went wrong here? How can I solve it?
Computer users would like to upgrade HDD to SSD for better performance. Most of them would like to clone HDD to SSD in case of reinstalling OS and applications. However, part of users may encounter the same problem like the scenario said, not able to boot from the new SSD. Why would that happened? Here we conclude two situations that may be the most possible reasons.
1. In a certain way, the error means the boot sector wasn’t copied. And you need to make sure that you copied all partitions.
2. If your cloned drive is a GPT disk, and your PC does not support UEFI mode, then the SSD won’t boot after clone.
As for different situations, we planed different solutions. Here we will introduce you the third party software, AOMEI Partition Assistant, which we will use for solving the problem “not able to boot from new SSD after SSD upgrading”.
AOMEI Partition Assistant is a hard disk manager that makes up for the lack of Windows Disk Management. It is also a great tool for disk upgrading.

Boot sector wasn’t copied is a common reason that cause the problem “not able to boot from new SSD” after upgrading. For this question, using a third party software to clone hard drive is the most secure way. The AOMEI Partition Assistant would help you copy system hard drive to SSD and boot from the SSD successfully.
Step 1. Connect the SSD to your PC or laptop via SATA adapter, make sure it can be detected. Install AOMEI Partition Assistant to your computer based on Windows environment. Launch it. In the main interface, click Disk Copy Wizard.
Step 2. It will give you two copy methods: Copy Disk Quickly, Sector-by-Sector Copy. Here we highly recommend the first method.
Copy Disk Quickly: will only copy the used space on the original hard drive. You can even copy HDD to an smaller SSD, as only as it large enough for storing data on the HDD.
Sector-by-sector Copy: will copy every byte on the old hard drive no matter it used or not. The target disk should be larger than the old hard drive.
Step 3. Choose the HDD as the source disk.
Step 4. Choose the SSD as the target disk. Here you need to check the option of “Optimize the performance of SSD”. That would optimize the SSD’s performance during the process.
Step 5. AOMEI Partition Assistant allows you to edit partitions on the target disk. If you do not want to adjust the size of partitions, you can repartition hard drive with AOMEI Partition Assistant later.
Step 6. Here gives you a note about how to boot from the cloned disk. Read it and remember it. Click Finish.
Step 7. When you back to the main interface, clickApply-> Proceed to execute the progress.
After the progress done, you can remove the HDD from your laptop and install the SSD, and then boot from the SSD. Or you can get into BIOS to change boot mode so that you can boot from the cloned SSD. Do as following steps:
1> Check the startup settings.
2> Press a specific key, usually Del for desktop andF2 for laptop, to enter BIOS settings.
3> Under Boot tab, make sure the cloned drive is first boot order.
However, many users still found that they cannot boot from the cloned SSD. And that may because the computer is not using the correct boot mode:
If your cloned drive is a GPT disk, you need to make sure your computer supports EFI/UEFI boot mode, otherwise, you need to convert GPT disk to MBR disk for booting successfully. If it is MBR disk, you need to set it to Legacy boot mode, or you need to convert MBR disk to GPT disk before you can boot from the cloned SSD.
AOMEI Partition Assistant allows you to convert boot disk from MBR to GPT or from GPT to MBR without losing data. Thus, if your cloned SSD won’t boot because of the incorrect boot mode, you can use it to convert disk according to your situation. Here takes an example of converting MBR disk to GPT disk:
Step 1. Connect the cloned SSD to the PC which installed AOMEI Partition Assistant. Launch the program. To convert disk from MBR to GPT, here you need to right-click the SSD, select Convert to GPT Disk.
Step 2. It will pop-up a window to confirm the operation. ClickOK.
Step 3. Finally, click Apply to execute the operation.
After conversion, install the SSD to your PC and boot from it. It should be worked.
AOMEI Partition Assistant can effectively solve the problem “not able to boot from new SSD”. If the two methods we introduced above did not solve your problem, you need to consider whether you need to repair the boot disk with Rebuild MBR function of AOMEI Partition Assistant for making your cloned SSD bootable.
